If you were traveling through London earlier this month, you may have come across quite a hair-raising surprise. Two living and extremely ominous-looking porcelain dolls were reported to have stalked many of the city's popular sites this month - including the Regents Street shopping district and Charing Cross station.

The two were dressed in pale pink Victorian-style clothing with identical blank states and auburn hair, and were often found either holding hands, holding onto a precious toy, or pushing along a black vintage stroller through popular neighborhoods.

Understandably, London commuters were a little freaked out.

Eventually, witnesses took to social media to share their videos and pictures, and many people began to hunt for the dolls' origin and identities.

Soon enough, it was announced that the dolls were sent out to help market Thorpe Park, a popular amusement park and tourist destination, and Minds Wanted, their upcoming collaboration with illusionist Derren Brown.

Opening next March, Minds Wanted is the world's first 'immersive psychological attraction' - a 13-minute ride that caters specifically to fans of psychological thrillers that the company vows will 'manipulate the human mind'.

In an official statement, Derren explained why they decided to go about such a creepy form of advertising:

"I believe we are moving toward a future where theme park attractions not only give you a physical experience but also play with your mind and the concept of what is real. The Victorian twin dolls, who have popped up around London this week, are just a taster of what my new attraction has in store for visitors to Thorpe Park next spring."

So now I want to know:

Would you guys want to write a 13-minute psychological thrill ride? Or have these dolls sufficiently scarred you for life?

Personally, I hate getting scared as a form of entertainment, but I'll be honest and admit that I'm at least pretty curious about how this mysterious ride is going to pan out.

@ABH13512 That's awesome. I've never been to Europe, but going to England and visiting Thorpe Park is very much on my list now. Especially after this addition to their park. It seems really interesting.
